Getting to grips with guitar effects can be a complicated business and there are so many different types that it can be difficult to know where to start. This Guitar FX basics series of video lessons is a brief introduction to the most common effects.
This video lesson focuses on pitch shift. A pitch shift pedal mixes the dry unaffected guitar signal with copy of the note being played but at a different pitch. Modern pitch shift pedals often feature intelligent pitch shifting, meaning once the key of the song is set, the pedal will harmonise along with your playing.
